Pinnable dummies are mannequin forms used in sewing, fashion design, or tailoring that allow pins to be easily inserted and hold securely. These dummies are typically covered in a foam or fabric layer that is soft enough to accept pins without resistance, yet firm enough to keep them in place. This feature is especially useful for draping fabric, fitting garments, and making precise alterations. Pinnable dummies are essential tools for designers who work with physical patterns and prototypes.
